I will need to migrate a wordpress site to Amazon EC2. I've never done this before and it's not my area of expertise, so I'm following this guide.
I am getting close to making the actual move (EC2 instance is setup, LAMP are ready, wordpress has a database ready, etc.).
My question is: after importing the wordpress SQL dump from the source site to EC2, copying files(plugins/themes/etc.) and replacing urls in the wp_options and wp_posts tables, will I be able to test before going ahead with the DNS settings ?
Once I copied the files and database from siteA to siteB and modified the wp options and posts tables to use siteB's IP, can I safely test the site without messing anything in wordpress even though the DNS settings are done yet ?
Is there a way to somehow use a 'shortcut'/sym link like thing so when I test files from siteB they temporarily use siteB instead of returning 404s ?
